Version 6.14.0

Greenwich v6.14.0 has been released on 22nd December, 2019.

The main update in this release is:

Greenwich New Turbine Model Library

• With consideration of the influence of components and controls on turbine model load and power curve, the new turbine digital model divides the original turbine model into two layers, the turbine model series layer and the turbine model layer. The turbine model series layer contains the information of basic property, turbine model, and applicable tower of the series, while the turbine model layer contains the information of operation mode, component configuration, and foundation load. This clearly-structured division lays a solid foundation for data transmission and management from wind farm and turbine design to delivery.
• As for the interaction, the new turbine library solves the efficiency defect of turbine import. By associating power curve and noise curve through the newly added operation mode, hiding empty folders in turbine library hierarchy, restructuring the turbine PK and turbine model import functions, and other dozens of interaction points, the user experience is distinctly enhanced.

In the successive releases, we will bring up the following features on turbine & wind farm design and delivery:

• Support mixed layout of load and reliability prediction calculation (COPQ).
• Support customized tower selection according to wind farm terrain and wind condition.
• Support auto generation of new project characteristic sheet based on the control information.

Besides, this release also consists of these optimizations:

• Released the new mesoscale grid with application of 5000+ mast data and the CNN technology;
• Added the regular layout function in layout optimization, supporting the regular layout in flat areas and offshore wind farms;
• Distinguished the syntheses and sector-wise CFD calculation to improve efficiency and diminish calculation resource waste.

Introduction of the New Turbine Digital Model

• Turbine model series: Aligning with the turbine model naming regulation of the company, this layer contains the turbine model series information of basic property, turbine model, and applicable tower.

1. Naming regulation:

   

2. Turbine model and applicable tower:

   2.1 Turbine model: A turbine model series might contain multiple turbine models. Refer to the next section for more information.

   2.2 Applicable tower: The tower parameters applicable to the turbine model series.

3. Basic property: Record the key information as manufacturer, platform, rated power, etc. and design wind conditions.

   

• Turbine model: The turbine model is defined by different hub heights and blade brand and type. This layer contains the turbine model information of basic information, operation mode, component configuration, and foundation load.

1. Naming regulation:

   

2. Operation mode: It represents a specific control strategy. In this layer, you can manage the versions, record configuration parameters as serration, and check and compare the difference of power curve and noise curve in different modes at the same time by associating the power curve and noise curve parameters under this control strategy.

3. Component configuration and foundation load:

   3.1 Component configuration: It is applied to record the key component information under the turbine model. The component parameters consisted here not only support the unit project calculation, but also are applicable in the load and reliability prediction calculation to be released later.

   3.2 Foundation load: The maximum foundation load at a hub height used in foundation computation. Through importing the new load matrix package which contains multiple sets of wind conditions and earthquake load parameters, the input time of load data is greatly decreased.

   Note

   Please contact Shanchao Hu to get the foundation load data.

4. Basic information: It mainly consists of the development status of turbine model, common turbine model configuration, hub height, and information relevant to blade.
